edimusrex has asked for the wisdom of the Perl Monks concerning the following question:

I've seen this question asked a few times and yet I haven't found a solution so I am going to ask again (specific to my question).

I have a simple web form in which I want the user to select a folder to upload (I only care about the contents of the folder). So my attempt to make this work is as followed:

#!/usr/bin/perl use strict; use warnings; use CGI; use Data::Dumper; my $q = CGI->new(); print $q->header; my $upload_folder = '/var/www/html/uploads'; my $name = $q->param('name'); my $email = $q->param('email'); my $comments = $q->param('comments'); my @files = $q->param('multi_files'); foreach my $upload(@files){ print "Upload this please -- $upload<br>"; my $upload_file = $q->upload($upload); if ($upload_file){ open (OUTFILE,">$upload_folder/$upload") or die $!;; binmode OUTFILE; while (<$upload_file>) { print OUTFILE; } } else { print "<b>Guess it's broken</b><br/>"; } } print "<p><b>Name</b> -- $name<br><b>Email</b> -- $email<br><b>Comment +s</b> -- $comments<br>"; print $q->end_html;
When I run the script all the parameters are correct, the files print out as expected but when I execute the upload query it returns blank. This is my first attempt at using CGI as I tend to use other languages to process forms.

Here is the code from the form just in case :

<html> <head> <title>Stupid Test Site</title> <script src="// +ery.min.js" ></script> </head> <body> <h1>This is a test</h1> <form action="/cgi-enabled/" method="POST"> Your Name: <input type="text" name="name"><br> Email Address: <input type="text" name="email"><br> Select PO folder: <input name="multi_files" type="file" we +bkitdirectory multiple /><br/> Comments:<br> <textarea name="comments" rows="5" cols="60"></textarea><b +r> <input type="submit" value="Send"> </form> </body> </html>
Any help on this issue would be greatly appreciated.

I've also posted this question on, sorry for the cross post --

----- Update -----

My error was in fact due to the missing enctype="multipart/form-data" in the form. I made some changes and tweaked some things based on all of you input. Here is my final working code :
#!/usr/bin/perl use strict; use warnings; use CGI; use Data::Dumper; use CGI::Carp qw( fatalsToBrowser ); use HTML::Entities qw/encode_entities/; use File::Copy qw' copy '; use File::Basename; my $q = new CGI; print $q->header; my $upload_folder = '/var/www/html/uploads'; my $name = $q->param('name'); my $email = $q->param('email'); my $comments = $q->param('comments'); my @files = $q->param('multi_files'); my @io_handles=$q->upload('multi_files'); my %file_hash; foreach my $item(@files){ next unless $item =~ /.+\/(M.+\.pdf)/; foreach my $sub_item(@io_handles){ if($item eq $sub_item){ $file_hash{$item} = $sub_item; } } } chdir $upload_folder or die "Cannot chdir to upload destination direct +ory: $!\n"; print '<ul>'; foreach my $key(keys %file_hash){ my $base = basename($file_hash{$key});# my $tmpfilename = $q->tmpFileName($file_hash{$key}); my $destFile = File::Spec->catfile($upload_folder,$base); copy( $tmpfilename, $destFile ) or die "Copy to ($destFile) failed +: $!\n"; print '<li>Sucessfully uploaded --- <b>', CGI->escapeHTML(basename +($key)), '</b></li>'; } print '</ul>'; print "<p><b>Name</b> -- $name<br><b>Email</b> -- $email<br><b>Comment +s</b> -- $comments<br>"; print $q->end_html;
So far so good. Thanks again for all the help. Will be posting my solution on Stackoverflow as well to close that out.
